Generic photo used for illustration purposes only Exact foot print substitute for MSA-0485 Cascadable, unconditionally stable MAR-4+ Aqueous washable CASE STYLE: VV105 Protected by US Patent 6,943,629 Typical Applications +RoHS Compliant Cellular The +Suffix identifies RoHS Compliance. See our web site for RoHS Compliance methodologies and qualifications PCN instrumentation General Description MAR-4+ (RoHS compliant) is a wideband amplifier offering high dynamic range. It has repeatable perfor - mance from lot to lot. It is enclosed in a Micro-X package. MAR-4+ uses Darlington configuration and is fabricated using InGaP HBT technology. Expected MTTF is 1,000 years at 85C case temperature. simplified schematic and pin description RF-OUT and DC-IN RF-OUT and DC-IN 3 RF IN 4 GND GND 2 1 RF IN GROUND Function Pin Number Description RF input pin. This pin requires the use of an external DC blocking capacitor chosen RF IN 1 for the frequency of operation. RF output and bias pin. DC voltage is present on this pin therefore a DC blocking capacitor is necessary for proper operation. An RF choke is needed to feed DC bias RF-OUT and DC-IN 3 without loss of RF signal due to the bias connection, as shown in Recommended Application Circuit. Connections to ground. Use via holes as shown in Suggested Layout for PCB GND 2,4 Design to reduce ground path inductance for best performance. Notes A.
